2. Objectives and learning outcomes
2.1 Objectives
The scope of the subject is to teach the students the fundamentals of geotechnics required for structural design, such as familiarity with and use of EC7. These include geotechnical categorization; types and contents of geotechnical documentations; geotechnical and structural design of piles for different loading types, design of soil-supported ground slabs along with the determination of the values of subgrade reaction modulus; design of pile-supported ground slabs and “rigid inclusion” slabs; structural design of excavation support structures, determination of soil reaction moduli along with their effect on deformations and internal forces; design of ground anchors; geotechnical questions of bridge abutments; and the basics of soil dynamics and geotechnical earthquake engineering.

3.3 Evaluation system
Total achievable during the semester100%
All three midterm tests and the three homeworks are failed if the sum points of the tests are less than the 50% of the obtainable points. It is also required to reach at least 50% of the points for every evaluation.
3.4 Requirements and validity of signature
There is no signature for this subjects.
3.5 Grading system
Determination of the final grade is according to the below described consideration:
The final grade is the sum of the percentage result of the midterm test and the homework tasks ( summing up to a maximum of 100 points.
GradePoints (P)
excellent (5)80<=P
good (4)70<=P<80%
satisfactory (3)60<=P<70%
passed (2)50<=P<60%
failed (1)P<50%
3.6 Retake and repeat
  1. The 2 midterm tests can be retaken once each. A second retake is possible for only one midterm test.
  2. The deadline for submitting homework is as follows: 1.MT: Week 10 Friday 23:59 2.MT: Friday 12th week 23:59 3.MT: Friday the 14th week at 23:59
  3. Deadline for additional homework: 1.MT: Week 11 Friday 23:59 2.MT: Week 13 Friday 23:59 3.MT: replacement week Friday 23:59 If someone does not meet the (partial) deadline for submitting homework 1 and 2 during the year, they cannot get a signature!
